＜Switch 2＞ Next, the switch 2 described in this case will be described. Fig. 2 is a schematic perspective view showing an example of the external appearance of the switch 2 described in the present application. Furthermore, in the specification of the present case, regarding the direction of the switch 2, facing Fig. 2, the front left side is expressed as front, the inner right side is expressed as rear, the inner left side is expressed as left, the right near front side is expressed as right, and the upper side is expressed as above. For the upper side, the lower side is expressed as the lower side, but for the convenience of description, the direction in which the switch 2 is assembled is not limited. As described above, the switch 2 is housed in an electronic device such as the operating device 1 as a micro switch, and the depression operation received by the depression operation portion 10 of the operating device 1 is received in the form of a pressing from the outside.

The switch 2 includes a housing 20 having a substantially rectangular parallelepiped shape. The housing 20 is formed by a base 20a at the bottom and a cover 20b at the top. On the upper surface of the housing 20, at a position to the left from the center in a plan view, a rectangular through hole 200 for inserting the pressing member 21 is opened. The pressing member 21 inserted through the insertion hole 200 is a member that receives pressure from the outside of the housing 20 and moves up and down in a range from the upper first position to the lower second position. The upper end of the pressing member 21 extends from the housing 20 The upper surface is prominent.

Furthermore, one connection terminal 22 that fixes the switch 2 to an external member such as a substrate, and four optical contact terminals 23a extending from an optical contact 23 (see FIG. 3, etc.) to be described later contained in the housing 20 The lower surface of the housing 20 protrudes.

The optical contact terminal 23a protrudes from the right end side of the lower surface of the switch 2 in front, rear, left, and right side by side. As the optical contact terminals 23a, a pair of first optical contact terminals 230a extending from the light emitting circuit 230 (refer to FIG. 3, etc.) protrudes rearward, and a pair of second optical contacts extending from the light receiving circuit 231 (refer to FIG. 3, etc.) The point terminal 231a protrudes forward.

In the switch 2 formed in this way, the pressing operation from the outside received by the operating device 1 is transmitted to the pressing member 21 in the form of pressing from the outside of the housing 20. The pressing member 21 receives the pressing from the outside and moves from the upper first position to the lower second position, and when the pressing from the outside is released, moves from the lower second position to the upper first position.

Next, the internal structure of the switch 2 will be described. Fig. 3 is a schematic exploded perspective view showing an example of the switch 2 described in the present application. FIG. 4 is a schematic cross-sectional view showing an example of a cross-section of the switch 2 described in the present application. Fig. 4 shows a cross section cut by a vertical plane including the line segment A-B shown in Fig. 2 from a front perspective.

The housing 20 of the switch 2 is provided with an area as a contact chamber that houses a contact mechanism for opening and closing an electric circuit. On the upper surface of the contact chamber, a through hole 200 penetrating from the outside of the housing 20 is opened, and a pressing member 21 is inserted through the through hole 200.

The contact mechanism housed in the contact room will be described. In the contact room, as a contact mechanism, in addition to the above-mentioned optical contact 23, a first locking piece 24, a second locking piece 25, a fixed member 26, and a movable member 27 are also arranged. The optical contacts 23 are arranged in the form of a light-receiving circuit 231 and a light-emitting circuit 230 in the front and rear of the lower right side of the contact room. The first locking piece 24 is arranged on the lower left side of the contact room, and the second locking piece 25 is arranged on the lower center side of the contact room. The first locking piece 24 and the second locking piece 25 are integrally formed with the connection terminal 22 under the housing 20. The fixing member 26 is arranged between the optical contacts 23 on the right side of the contact room. The movable member 27 is arranged to extend left and right in the contact room, and is locked by the first locking piece 24 and the second locking piece 25.

The optical contact 23 includes a light emitting circuit 230 that emits light and a light receiving circuit 231 that receives light emitted from the light emitting circuit 230. The light emitting circuit 230 is configured using a light emitting element 230b such as a light emitting diode (LED), and has a pair of first optical contact terminals 230a. The light-receiving circuit 231 is configured using a light-receiving element 231b, such as a photodiode (PD) and a phototransistor (PT), and has a pair of second optical contact terminals 231a. The light-emitting element 230b of the light-emitting circuit 230 and the light-receiving element 231b of the light-receiving circuit 231 are arranged so as to face each other so that the light-receiving circuit 231 receives light emitted from the light-emitting circuit 230. The light-emitting circuit 230 is energized by passing through the first optical contact terminal 230a, and the light-emitting element 230b of the light-emitting circuit 230 emits light. When the light-receiving element 231b of the light-receiving circuit 231 detects light, the energization status changes, so the second optical contact terminal 231a outputs a conduction signal based on the change in the energization status caused by light reception.

The fixing member 26 is in the shape of a thin plate erected so that the normal direction becomes the front-rear direction, and is located in front of the light-emitting circuit 230 of the optical contact 23 and behind the light-receiving circuit 231, separated from the light-emitting circuit 230 and the light-receiving circuit 231. Open and erect. The lower part of the fixing member 26 is a light-shielding plate 260 provided with a substantially circular transmission hole 261 through which the light of the optical contact 23 passes, and the upper part is bent in a wrist shape to form a substantially U-shaped opening on the left side. The fixing member 26 is arranged so that the movable contact portion 270 on the right end side of the movable member 27 is sandwiched from the top and bottom by the U-shaped opening in the upper part. The upper inner side of the opening of the fixed member 26 becomes the first abutment portion 262, which is provided for the movable member 27 when the pressing member 21 is at the first position and the movable member 27 is not pressed by the pressing member 21. The movable abutting portion 270 touches. The inner lower part of the opening of the fixed member 26 becomes the second abutting portion 263, which is provided for the movable member 27 when the pressing member 21 is at the second position and the movable member 27 is pressed by the pressing member 21 The movable abutting portion 270 touches. The movable contact portion 270 of the movable member 27 extends so as to enter between the first contact portion 262 and the second contact portion 263 of the fixed member 26. With regard to the first contact portion 262 of the fixed member 26, the front end extending to the left protrudes downward so that the movable member 27 that is not pressed can easily touch, and the movable member 27 abuts the first contact portion 262 from below. As for the second abutting part 263 of the fixed member 26, the central part protrudes upward so that the pressed movable member 27 is easily touched, and the movable member 27 abuts the second abutting part 263 from above. In order to generate a suitable click sound, the fixing member 26 is preferably formed using a metal material, and may be formed using materials such as organic material rubber, inorganic material rubber, and hard resin. In addition, the fixing member 26 may be appropriately replaced in order to adapt the click sound, for example.

The movable member 27 is a member made of metal such as stainless steel (SUS) in a plate shape extending in the left-right direction in the contact room. The left end side of the movable member 27 becomes a fixed end that is locked to the first locking piece 24 and functions as a swing fulcrum 271. The right end side of the movable member 27 is a movable contact portion 270 that moves as a free end between the first contact portion 262 and the second contact portion 263 of the fixed member 26. In addition, the right end side of the movable member 27 is a substantially rectangular light-shielding sheet 272 that is bent downward from the movable contact portion 270. The light-shielding sheet 272 is formed such that the normal direction becomes the front-rear direction, and a substantially rectangular transmission window 273 through which the light of the optical contact 23 is transmitted is opened. The light-shielding sheet 272 is positioned in front of the fixing member 26 and behind the light receiving circuit 231 of the optical contact 23, in a state of being separated from the fixing member 26 and the light receiving circuit 231, and is located between the fixing member 26 and the light receiving circuit 231 position. Furthermore, the movable member 27 is formed with an urging portion 274 that functions as a return spring and is formed by pressing and bending the vicinity of the center into an arc shape. The tip of the urging portion 274 is locked in the center formed in the contact chamber. The second locking piece 25 nearby. The urging part 274 generates a reaction force against the pressing of the pressing member 21.

In the contact mechanism configured in this way, the pressing member 21 receives pressure from the outside and moves downward to press the movable member 27 downward. When the movable member 27 is pushed down, the movable abutting portion 270 on the right end side of the free end of the movable member 27 descends, and the movable abutting portion 270 touches the second abutting portion 263 of the fixed member 26. When the movable abutting portion 270 of the movable member 27 made of metal touches the second abutting portion 263 of the fixed member 26, a metallic sound is generated. The user recognizes the metallic sound generated by the movable member 27 touching the fixed member 26 as a click sound. In addition, as the right end side of the movable member 27 descends, and the light shielding sheet 272 of the movable member 27 descends, the light of the optical contact 23 passes through the transmission window 273 of the light shielding sheet 272 opened in the movable member 27, and the circuit is closed. Output the pilot signal to external electronic equipment.

When the pressing of the pressing member 21 is released, the movable member 27 is urged to the upper side by the reaction force of the urging portion 274. By urging the movable member 27 to the upper side, the pressing member 21 moves upward. In addition, by urging the movable member 27 to the upper side by the urging portion 274, the movable abutting portion 270 located on the right end side of the movable member 27 rises and contacts the first abutting portion 262 of the fixed member 26. In addition, as the right end side of the movable member 27 rises, and the light shielding sheet 272 of the movable member 27 rises, the light of the optical contact 23 is blocked by the light shielding sheet 272, and the circuit is opened.

The circuit opening and closing by the optical contact 23, the fixed member 26, and the movable member 27 will be further described. 5A and 5B, and FIG. 6 are schematic cross-sectional views showing an example of the cross-section of the switch 2 described in the present application. FIGS. 5A and 5B are enlarged and show cross sections cut by a vertical plane including the line segment C-D shown in FIG. 2 from an upper right perspective. Fig. 6 shows a cross section cut by a vertical plane including the line segment C-D shown in Fig. 2 from a viewpoint from the right. 5A shows that the pressing member 21 is in the first position, and the pressing of the pressing member 21 is released and the circuit is opened. FIGS. 5B and 6 show that the pressing member 21 is in the second position, and the pressing member 21 is pressed and the circuit is opened. Closed on state.

When the pressing of the pressing member 21 is released, as shown in FIG. 5A, the light-shielding sheet 272 of the movable member 27 rises, and the transmission window 273 of the light-shielding sheet 272 deviates from the light-emitting element 230b of the light-emitting circuit 230 to the light-receiving element of the light-receiving circuit 231 231b light path. Therefore, although the light emitted from the light-emitting element 230b of the light-emitting circuit 230 passes through the transmission hole 261 of the light-shielding plate 260 opened in the fixed member 26, it is shielded by the light-shielding sheet 272 of the movable member 27, and therefore does not reach the light receiving circuit 231. In the element 231b, the circuit is in an open state.

When the pressing member 21 is pressed, as shown in FIGS. 5B and 6, the light-shielding sheet 272 of the movable member 27 is lowered, and the light-emitting element 230b of the light-emitting circuit 230 passes through the light-receiving element 231b of the light-receiving circuit 231. In the through window 273 of the shading sheet 272. Therefore, the light emitted from the light-emitting element 230b of the light-emitting circuit 230, as shown by the hollow arrow in FIG. 6, passes through the transmission hole 261 of the light-shielding plate 260 opened in the fixed member 26, and then passes through the light-shielding sheet 272 opened in the movable member 27. The transmission window 273 reaches the light receiving element 231b of the light receiving circuit 231, and the circuit becomes a closed conduction state.

As described above, the switch 2 described in the present application uses the movable member 27 having the light-shielding sheet 272 formed by molding a metal material such as SUS, and thereby it is movable in accordance with the depression operation of the depression operation portion 10 of the mouse. The contact piece touches the fixing member 26 to generate a metallic sound. This provides an excellent effect that the user can recognize the generated metallic sound as a clicking sound. In particular, metallic sounds are easy to recognize as click sounds, and are suitable for fields requiring rapid response such as e-sports.

In addition, the switch 2 described in the present application uses a movable member 27 having a metal light-shielding sheet 272. Due to the high light-shielding properties of metal, for example, even the movable member 27 formed by molding a thin plate of 0.1 mm or less is also effective The outside of the transmission window 273 blocks light and does not allow light to pass through. The light blocked by the light-shielding sheet 272 means light emitted from the light-emitting circuit 230 in various directions, light entering the housing 20 from the outside, and various lights such as reflected light, scattered light, and stray light of these lights. Due to the high light-shielding property, the light-shielding sheet 272 can be thinned to reduce the size of the switch 2. In addition, since the light-shielding property is high, it exhibits excellent effects such as suppressing noise generation and improving accuracy.

Furthermore, in the switch 2 described in this application, the movable contact portion 270 located on the right end side of the movable member 27 operates between the first contact portion 262 and the second contact portion 263 of the fixed member 26. Thereby, the movement range of the movable contact portion 270 of the movable member 27 is restricted, for example, it is possible to suppress the warpage of the movable member 27 to stabilize the movement, etc., thereby exhibiting excellent effects.

Therefore, the above-mentioned embodiment is only a simple illustration in all aspects, and is not a limited explanation. The technical scope of the present invention is illustrated by the scope of patent application, and is not limited by the text of the specification. Furthermore, all the modifications and changes belonging to the equivalent range of the patent application are within the scope of the present invention.

For example, the fixing member 26 used for the switch 2 is not limited to the shape described in the above embodiment, and can be designed appropriately. FIG. 7 is a schematic front view showing an example of the appearance of the fixing member 26 included in the switch 2 described in the present application. The fixing member 26 illustrated in FIG. 7 faces the figure and extends downward from the lower left side, and becomes a connection terminal 22 protruding downward from the vicinity of the center of the lower surface of the housing 20 (protruding in the pressing direction of the pressing member 21 ). By integrally molding the connection terminal 22 and the fixing member 26, the area of the light shielding plate 260 of the fixing member 26 becomes larger. Therefore, the light shielding property can be improved to shield various light, suppress noise generation, and improve accuracy.

In addition, in the above-described embodiment, a mouse is exemplified as the operation device 1, but the present invention is not limited to this, and can be applied to various devices such as electric tools and on-board switches.

Furthermore, in the above-mentioned embodiment, the fixing member 26 of the switch 2 has the first contact part 262 and the second contact part 263. However, the present invention is not limited to this, and it may be designed without the first contact part. In the form of the part 262, even if it does not have the first contact part 262, as long as it has the second contact part 263, a click sound can be generated.

Furthermore, in the above-mentioned embodiment, as the optical contact 23, the form of the transmissive optical contact 23 in which the light emitted from one circuit is received by the other circuit is shown, but the present invention is not limited to this, and reflective The type of optical contacts 23 and the like are developed in various forms.

Furthermore, in the above-mentioned embodiment, the movable member 27 and the light-shielding sheet 272 are shown as an integral form, but the present invention is not limited to this. As long as the light-shielding sheet 272 is operated in accordance with the shaking of the movable member 27, the light-shielding sheet 272 may be combined with the movable member. 27 formed separately. Furthermore, even when the movable member 27 and the light-shielding sheet 272 are formed separately, the effect of the present invention is exerted by being configured as follows: the movable member 27 and the light-shielding sheet 272 are formed of a metal material. Either one or both of them contact the fixing member 26 with shaking, and generate a metallic sound as a click sound.
